UNITED STATES PATENT OFFICE JOHN POLAGHEK, OF NEW YORK, AND JULIUS A. J'EPSEN AND EDMUND PEREMI, OI ELMHURST, NEW YORK, ASSIGNORS 'IIO GENERAL BRONZE CORPORATION, OF LONG ISLAND CITY, NEW YORK, A. CORPORATION OI NEW YORK FLAT SPRIN'G ANTIRATTLIN'G DEVICE FOR WIN'DOWS Application filed May 24, 1929. Serial N0. 365,611.

This invention relates to windows and directly to means whereby the" movable sashes of wlndows may be prevented from rattling or moving laterally in their frames.

Our invention may be employed in connection with any window construction with slight changes of form, but is especially applicable to the modern bronze or metallic windows now in general use in office and bank buildings and other better class structures.

In these metallic windows there is more or less lateral movement of the sashes in the frames, sometimes causing rattling noises not pleasant to the ear; and further, no matter how carefully the frames and sashes are assembled there often occurs faulty interengagement of the fixed parts and the sashes allowing cold air and dust to enter It is the object of our present invention to A provide means concealed within the sash said devices being preferably formed with contact extensions having yielding thrust engagement with the inner faces of the usual outer and inner guide strips or shoulders, thus acting to urge the inner faces of the sash stiles against the parting strip to form a sealed joint therewith to exclude cold air and dust and to prevent rattling or lat- I eral movements of the sash in the window frame.

In the drawings illustrating our invention we employ similar reference characters to designate corresponding parts throughout the several views, in which:

Fig. 1 is an outside elevation of a window with the elements of our invention applied in operative position, parts being broken p'way to show one of said elements in full mes.

Fig. 2 is an enlarged vertical cross sectlonal elevation of the window, the section belng about on the line 2-2 of Fi 1.

Fig. 3 is a further enlarged orizontal cross sectional plan view through one side of the window about on the skip broken lines 3-3 of Fig. 2.

Fig. 4 is a detail perspective view of a form of the resilient element employed.

To clearly illustrate our invention we have shown in the drawings a well known type of metallic window construction embody ng a frame'lO, parting strips 11, outer and inner guides 12 and 13, sashes 14, an upper rail 15, a lower rail 16, meeting rails 17 and side stiles or rails 16.

To advantageously arrange the resilient elements 19, concealed within the hollow rails of the window to properly function as desired, we place them in a preferably horizontal position within the opposite ends of the top, bottom and meeting rails 15, 16, 17 and 1 7 and secure the inactive ends thereof to the inner faces of the outer webs of said rails by rivets 20 or by other means.

A preferred construction of the resilient elements is shown in detail in Fig. 4 of the drawings and embodies a fiat spring comprising a shank 21, perforated to receive a rivet 29 and an angular bent contact extension 22. The shank 21 is preferably precurved in a direction opposite to the bend of the extension 22 to erect a constant yielding thrust on the inner faces of the guides 12 and 13 against which the extensions 22 of the spring shanks 21 operatively rest to force the window sashes lnwardly against the parting strip 11 to provide an air and dust-proof seal and to prevent rattling of the parts in any position, whether the sashes be closed or opened to any degree.

. We, finally, may alsoemploy a regulating set screw 23, in connection with our resilient elements 19, being threaded throu h an outer web of the rail and engaging t e element 19, as shown, such set screw being for the purpose of adjusting the tension of the anti-rattling device to relieve the extreme pressure on metal to metal contact and still havesufiicient strength to withhold the wind pressure or any other jar occurring to the window. By means of the application of the adjusting screw the tension of the spring may be. regulated for easy or heavier operation of the window, as may be desired.

It is also especially remarked that the anti-rattling device .in its preferred embodiment is entirely concealed between the sash and jamb parts of the window.

It is understood that changes and variations may be made in the parts of the invention and we reserve our rights to such changes and modifications-as are within the spirit of the invention and the scope of the annexed claims.

For instances, one modification is to insert the fiat spring vertically in the vertical stiles of the sashes with the said contact extensions traveling broadside against the said guide faces instead of edgewise.

What we claim as new, is:

1. In a window embodying a frame having outer and inner' guides, a centrally positioned parting strip, and sashes having upper, lower and meeting rails and side stiles, resilient elements arranged horizontally within the said rails of the window and having thrust engagement with the inner faces of said guides to move the sashes into intimate contact with said parting strip.

2. In a window embodying a frame having outer and inner guides, a centrally posi-' tioned parting strip, and sashes having upper, lower and meeting rails and side stiles, resilient elements arranged horizontally within the said rails of the window and havingv thrust engagement with the "inner faces of said guides to move the sashes into intimate contact with said parting strip, said rails having contact webs and said resilient element being secured'to the inner faces of outer webs on said rails.

3. In a window embodying a frame having outer and inner guides, a centrall positioned parting strip, and sashes aving tally on the said rails of the window and having thrust engagement with the inner' faces of said guides to move the sashes into intimate contact with said parting strip said resilient elements comprisin lea sprin .with angularly bent termina s havingdteir free ends in contact with said 5. In a window, having a vertically slid- I ing sash with horizontal rails, and a guide for said sash, resilient elements horizontally arranged on said rails and enga ing saidguide to permanently urge the sas in a desired lateral direction.

6. In a window, having. a vertically sliding sash with horizontal rails, and a guide for said sash, resilient elements horizontally arranged on said rails and engaging said guide to permanently urge the sash in a arranged on said rails and engaging said upper, lower and meeting rails and side-- ide to permanently urge the sash in a desired lateral direction, said resilient elements comprising leaf springs with angularly bent terminals.

8. In a window embodying a frame having outer and inner guides, a'centrally po-v sitioned parting strip, and sashes having upper, lower and meeting rails and side stiles, resilient elements arranged on said rails of the window and having thrust engagement with the inner faces of said guides to move the sashes into intimate contact with said parting strip, said rails having contact and outer webs and said resilient element being secured to the inner faces of said outer webs on said rails to thrust said contact webs into intimate contact with the faces of the said parting strip.

9. In a window embodying a frame having outer andinner guides, a centrally positioned parting strip, and sashes having upper, lower and meeting rails and side stiles, resilient elements arranged on said rails of the window and having thrust engagement with the inner faces of said guides to move the sashes into intimate contact with said parting strip and tension members to adjust the tension of the resilient elements and re ulate the contacting of the said rails with t esaid parting strip.
